- the present invention relates to mirror assembly for mounting onto a vehicle, and more particularly, to a mirror assembly having an ellipsoidal-shaped reflective surface, such that when two mirror assemblies are mounted on each front fender of the vehicle, the driver has a complete field of vision of the front and both sides of the vehicle.
- U.S. Pat. No. 4,730,914 by Stout et al discloses a variation of the Schmidt and Hutchinson design. Although an irregularly shaped convex mirror with a plurality of radii of curvature is disclosed, the preferred design is a sphere having a ten inch radius of curvature.
- the primary advantage of the mirror assembly of the present invention is that it reduces dramatically the size of the "blind spots" behind the mirror assembly.
- Another advantage of the mirror assembly of the present invention is that it enhances the field of view and the visibility about the vehicle.
- the mirror assembly of the present invention preferably is mounted onto each front fender of the vehicle.
- the mirror assembly is designed to improve the field of view of a school bus, the mirror assemblies can be readily adapted for use on any larger vehicles, including but not limited to cars, station wagons, trucks, trailers, trains, recreational vehicles, aircraft, boats, and the like.
- the reflective surface of the mirror has a generally convex geometry, and preferably has the shape of a portion of an ellipsoid.
- ellipsoid refers to a solid geometric shape having a section which is essentially elliptical in shape.
- the ellipsoid of the present invention preferably has a variable radius of curvature across the entire surface thereof.
- the reflective surface provides a field of view along the vertical axis normal to the driver's line of sight to the reflective surface of about from 180° to 220°.
- the reflective surface is defined by truncating a first plane through the ellipsoid.
- the first plane removes a major portion of the top of the ellipsoid, resulting in the reflective surface having a generally flattened top portion.
- the reflective surface is further defined by truncating a second plane through the ellipsoid.
- the second plane is essentially normal to the first plane, and removes the rear half portion of the ellipsoid.
- the reflective surface is mounted with a slight upward tilt.
- the diameter of the mirror disclosed in U.S. Pat. No. 4,436,372 is preferably about eight (8) inches.

- the mirror 12 is mountable onto an exterior front surface of a vehicle.
- two of the mirror assemblies 10 are mounted on the vehicle; one each on the right and on the left front fenders in such a manner that the "blind spot" behind each mirror 12 is fully disclosed in the other mirror.
- the mirror 12 has a transparent outer surface 20 formed thereon.
- the transparent outer surface 20 is made of acrylic plastic.
- the transparent outer surface 20 is about 0.125 inches thick.
- the mirror 12 has a curved inner liner 26 which is coated with a light reflective coating, such as about 0.7 mils thick to form an ellipsoidal-shaped light reflecting surface.
- the light reflective coating may be formed by aluminum deposition on the inner liner.
- the mirror 12 has a reflective surface 14 having a generally ellipsoidal shape.
- the reflective surface 14 is defined by truncating a first plane 30 therethrough.
- the first plane 30 removes a significant portion of the top of the reflective surface 14 (preferably, passing through the center of the ellipsoid), resulting in the reflective surface 14 having a generally flattened top portion 32.
- the reflective surface 14 is further defined by truncating a second plane 34 through the ellipsoidal mirror 12.
- the second plane 34 is essentially normal to the first plane 30 of truncation, and preferably removing the rear half portion 36 of the mirror.
- the mirror frame 16 has two essentially flat surfaces 40 and 42, each of which are substantially coplanar with both the first plane 30 and the second plane 34.
- the frame 16 has a first gasket 44 extending continuously beyond and around the top portion 40 of the reflective surface, and the frame 16 has a second gasket 46 extending continuously beyond the rear portion 42 of the reflective surface 14.
- the gaskets 44 and 46 are preferably formed with the same material as the outer surface 20 and is integral with the body of the mirror.
- the gaskets 44 and 46 are preferably made of a rubber or vinyl, or made of a metal and coated with rubber or vinyl.
- the reflective surface 14 may be any geometric shape having a plurality of radii of curvature, preferably, the reflective surface 14 is generally the shape of a portion of an ellipsoid. It has been found that any ellipsoid provides a full field of view with minimal distortion.
- the first plane 30 and the second plane 3A will reduce the surface area of the reflective surface to about one quarter of the total surface area of the ellipsoid.
- the diameter 50 of the reflective surface is normal to the height 52 or H of the reflective surface.
- the reflective surface provides the driver with a field of view which is in the range of from 180° to 220°.
- the reflective surface 14 is mounted with a slight upward tilt.
- the tilt enables the flat top surface 40 of the mirror to be in substantial alignment with the line of sight of the driver.
- the rear portion of the reflective surface has a second plane of truncation. As shown in FIG. 5, the section formed by the second plane of truncation has the shape of a semicircle. This ratio of the diameter 50 to the height 52 or H is in the range of 2.0 to 6.0.
- FIG. 6 is a bottom view of the reflective surface of the mirror and has the general shape of an ellipse.
- the elliptical convex reflector surface 14 has its focal points located on the diametrical plane of the major axis.
- the reflector surface 14 includes a first, a second, and a third reflector surface portions which each correspond to a different radius of curvature of the ellipsoid.
- the mirror 12 produces a continuous image to a viewer who is positioned in alignment therewith, which is larger in the center and smaller near the edges thereof.
- the surface 14 produces no severe distortion and the viewer is able to overcome the partial distortions caused by the different radii of curvature and interpret the image formed thereon.
- the rigid tubular member 18 has an upper portion 60 and a lower portion 62.
- the upper portion 60 of the tubular member is attached to the fender and the mirror frame 16.
- the tubular member 18 extends about the fender in such a manner that the reflective surface 14 is visible to the driver when the driver is seated in a position behind the steering wheel.
- the tubular member 18 has a plurality of radical bends 59 therein, to insure the proper positioning of the reflective surface.
- a radical bend 59 is an angle of 90° or more.
- the tubular member 18 serves to damp the vibration of the mirror 12 during vehicle movement.
- the radical bends 59 separate the mirror vibrations which would otherwise impair the driver's vision.
- the mirror assembly 10 is preferably mounted even with the hood line of the vehicle for purposes of ballast.
- the center of gravity of the mirror assembly 10 preferably lies within the tubular member 18 which serves to balance the assembly 10, and minimize vibration of the assembly 10 caused by movement of the vehicle.
- the mirror assembly 10 of the present invention also includes a mounting means 24 and an attaching means 22.
- the mount 61 disclosed in this patent is preferably the mounting means 24 and the attaching means 22.
- the mount 61 can similarly be used for securing to flat surfaces, by using a base member 80 having a flattened mounting surface 82.
